I'm white, was in an interracial relationship with a second generation middle eastern guy. Things went great for the first 5 months of dating. I really liked so many of his individual qualities. The more I got to know "of" his family though, the more I realized it would never work out. I saw "of" because I never was actually allowed to meet the family until the point that "engagement was on the table" because his family saw meeting me as a girlfriend, or even a friend who is a girl, as inappropriate.
When I asked if his parents would not approve of me because of my race, he hesitated and said, "well.. they want me to marry an Arab girl. But white is a close second." Some people don't care about their in-laws and if they like/don't like you. There were a lot of cultural traditions his family followed that I respect, but some other things I knew I could not handle. Like how women in his family were treated. It matters to me to have similar family values as my future partner, and his in-laws, so I ended it the next day.
